IMPROVEMENT IN MILK-FAILS.

Specification forming part of Letters Patent No. 197,836, dated December4,1877; application filed September 1. 1877.

' venience in the use of the ordinary wiregauze strainers in milk-pailsas'heretofore made, with a single diaphragm set in a frame-work in themilk-pail, and it has long been apparent to me i that this device wasimperfect, as it allowed the motes and other foreign substances to passthrough it, especially hairs, which, in the spring-time particularly,are very annoying to the dairyman. From the inconveniences thusencountered by me in practice came the device herein described, inventedby me to obviate them, which I have found, after a thorough practicaltest, to be a sure remedy, making a perfect strainer.

The following is a description of. the construction of my strainer,referring to the ac conipanying drawings, in which- Figure 1 is avertical section through the strainer and front upper portion of a pail.

Fig. 2 is a front view of the strainer and cap.

Fig.3 is awire-gauze diaphragm detached.

The pail A may be of any convenient size orform. From the cap or shieldin front a nozzle, a, projects, upon the end of which there is acylindrical ring, b, permanently attached, the outer end of which ringis made with a broad annular seat by the bead b, as clearly seen inFig. 1. On this ring a screw-thread is cut, and an annular cap, 0,screws onto it. Between the end of the ring I) and cap 0 a series ofwire-gauze diaphragms are placed, one uponanother, (I have found wireforming the same by a rimof solder, d

the best results from the use of three diaphragms, generally,) as shownin Fig. 1,wherescrewed down tight upon the permanent ring b, firmly,holding the d aphragm-s by their edges between them. Three diaphragmswill effectually prevent the hairs passing through, and are sufficientfor all ordinary occasions, the interstices forming an irregular passagefor the liquida result not obtainable with a single wire-gauze. I I

The diaphragms, being separate from each other, are easily and perfectlycleanedani1nportant point with dairymen.

Having thus fully described my improvement, I claim v l. The compounddiaphragm, composed of a series of layers of wire-gauze superimposedupon-each other, and secured firmly in place by the single cap andscrew, as described.

2. Uniting and consolidating the edges of the wire-gauze by a rim ofsolder, as herein specified, and for the purposes set forth.

HENRY DODGE.
